Detailed description of the invention
The present invention relates to a kind of control system for manipulating crane in fabrication shop.With reference to electric bridge (EOT) hoisting crane 101 of the load of the machine tool 103 in the sheet metal press device for transporting in such as such as car manufacturing factory and so on, present invention is described.Exemplarily, the weight of mould 103 can be respectively 3 tonnes to 4 tonnes.Hoisting crane 101 is controlled by crane operator and one or more hoist cable operator.
As shown in Figure 2, comprise can the crane span structure 109 of X (north/south) direction movement along the longitudinal direction for hoisting crane 101.The crane carriage unit 111 of accommodating jack up unit 113 is arranged on crane span structure 109 in a movable manner, and can transversely advance in direction Y (east/west) direction.Crane span structure 109 has three work speeds, and crane carriage unit 111 has two work speeds.Jack up unit 113 has for performing three work speeds promoting and fall.
The lifting frame 115 of rectangle is supported by jack up unit 113, and four hoist cable 117a to 117d are permanently connected to the turning of lifting frame 115.Hoist cable 117a to 117d has the hook (not shown) of the far-end attaching to hoist cable 117a to 117d regularly separately for the corresponding attachment point 119a to 119d be attached on mould 103.Operation jack up unit 113 makes lifting frame 115 rise and fall, and makes mould 103 rise and fall thus.Once make mould 103 rise, just transport mould 103 by making crane span structure 109 and/or crane carriage unit 111 move.
Crane operator uses the wireless remote control unit 121 being combined with visual display unit 123 to control hoisting crane 101.RCU 121 and the Central Processing Unit (CPU) 125 be arranged on crane span structure 109 carry out radio communication.
Crane carriage unit 111 is provided with infra-red thermal imaging pick up camera 127 with the work area 129 of the encirclement mould 103 shown in surveillance map 3.Crane carriage unit 111 is also provided with First look pick up camera 131 to be created on the video flowing of work area 129 shown in plan view.To provide the alternative view of work area 129 on contrary two ends that second video camera 133 and the 3rd video camera 135 are arranged on crane span structure 109.Video camera 131,133,135 exports video data to Central Processing Unit (CPU) 125.
Central Processing Unit (CPU) 125 is connected to Wireless Transmitter and the antenna 137 of the transmission over radio for carrying out video data.The video data transmitted is received by RCU 121 with the video data shown on visual display unit 123 from the first video camera 131.RCU 121 can optionally be configured to allow crane operator's selection for being presented at the video data exported by each in vision camera 131,133,135 on visual display unit 123.Long range radio receiver 139 also receives the video data transmitted, and these data are stored in field network 143 on joining memory storage 141.Video data can be stored reach such as 30 days operating time to provide reference library.
Work area 129 comprises the internal security region 145 and external security region 147 that arrange concentrically.As described herein, whether Central Processing Unit (CPU) 125 is present in the control of changing hoisting crane 101 in internal security region 145 and external security region 147 according to operator's (or other people).Can use from one or more the video data in vision camera 131,133,135 whether to detect the existence of operator, but the motion of attached object may cause high background noise level.Therefore, present embodiment utilizes thermal imaging camera 127 whether to detect the existence of operator.
As shown in Figures 3 and 4, thermal imaging camera 127 verticallydownwardly points to and generates the thermal imagery around the region of mould 3.Internal security region 145 is defined as the region around mould 103, is generally the outward flange die width exceeding mould 103.External security region 147 is equivalent to exceed another die width of internal security region 145.Will be appreciated that, the size in internal security region 145 and external security region 147 may change due to different application.The circumference of mould 103 can be limited in advance or can such as use the video data from First look pick up camera 131 dynamically to determine the circumference of mould 103.
In operator detected in outside safety zone 147, notify crane operator, such as, notify crane operator by bright light.The example of this lamp is shown in Figure 7.When operator enters internal security region 145, Central Processing Unit (CPU) 125 can make the sideway movement of crane span structure 109 and crane carriage unit 111 stop or suppressing the sideway movement of crane span structure 109 and crane carriage unit 111.Make jack up unit 113 can carry out falling operation, but lifting operation is stopped.Lifting operation is made to stop guaranteeing that not making load rise people close to jack up unit during mould 103 113 also reduces waving of load thus.
As described in this article, Central Processing Unit (CPU) 125 in response to the output of only thermal imaging camera 127 or can carry out work in response to the output that thermal imaging camera 127 combines with rotary encoder and/or load transducer.Such as, when thermal imaging camera 127 detects the operator be in internal security region 145, Central Processing Unit (CPU) 125 can be configured to only just make when load being detected by load transducer the sideway movement of hoisting crane 101 stop or suppressing the sideway movement of hoisting crane 101 and/or make the operation of jack up unit 113 stop or suppressing the operation of jack up unit 113.This set enables operator in internal security region 145, work to guide lifting frame 115 to enter position for being attached mould 103.Make the operation of the hoisting crane 101 only just stopping or suppressed when load is initially put on hoisting crane 101 and operator detected in internal security region 145.Represent shown in Figure 5 in response to the truth table A of the mode of operation of the hoisting crane 101 of detected parameter.Be described to the safety control system implemented in hoisting crane according to the present invention now.
Altitude datum (H1)
Rotary encoder (not shown) is provided with the advanced positions of the height monitoring jack up unit based on the hook be arranged on hoist cable 117a to 117d in jack up unit 113.Altitude datum H1 (shown in Figure 3) is defined as the operation for controlling hoisting crane 101.In the present embodiment, altitude datum H1 is set to the height that two stacking moulds 103 add one (1) rice, to provide space above stacking mould 103.Will be appreciated that, this altitude datum H1 can be corrected the specific mould field or mould field in a row that work for hoisting crane 101 wherein.Altitude datum H1 can such as set for this specific hoisting crane 101 according to the mould field covered by specific hoisting crane 101.Cover the altitude datum H1 comprising the hoisting crane 101 of the mould field of multiple stacking mould 103 (such as two or three stacking moulds 103) likely large than covering the altitude datum H1 with the hoisting crane 101 of the mould field of single stack mold 101.
When above hook is in altitude datum H1, hoisting crane 101 works in a conventional manner and does not advance to the side direction of crane span structure 109 or crane carriage unit 111 and limits.But when rotary encoder judges that hook is in below altitude datum H1, the motion of translation of crane span structure 109 and crane carriage unit 111 is all suppressed.Especially, Central Processing Unit (CPU) 125 start through restriction or through suppress traveling mode (being also referred to as " creeping " pattern), through restriction or in traveling mode through suppressing, crane span structure 109 and crane carriage unit 111 be the mobile progressive distance preset in response to each independent input completed at RCU 121 by crane operator.Therefore, the distance preset of all advancing when crane span structure 109 and the control of crane carriage unit 111 on each RCU 121 are worked, such as, crane span structure 109 and/or crane carriage unit 111 are advanced and are reached the pulse of one (1) second.When starting the traveling mode through suppressing, the rise of jack up unit 113 and fall operation and remain unaffected.When starting the traveling mode through suppressing, Central Processing Unit (CPU) 125 can reduce the gait of march of crane span structure 109 and/or crane carriage unit 111 but not implement gradual advancing.
Through suppress traveling mode be enabled in the swing and the sideway movement reducing lifting frame 15 that alleviate load when hook is in below altitude datum H1.Crane operator is made to be confident of lifting frame 115 to be positioned to be greater than directly over mould 103 At The Height of altitude datum H1.Then can lifting frame 115 be lowered to below altitude datum H1 by jack up unit 113 and accurately complete little sideway movement to come positioned-lifting framework 115 and hook relative to mould 103.Lifting frame 115 and mould 103 vertically upright can be elevated to above altitude datum H1 by crane operator subsequently before lifting frame 115 and mould 103 carry out any sideway movement.Because in described hook is hooked in the top remaining in altitude datum H1 during side direction is advanced, the possibility therefore making in described hook hook surprisingly tangle mould 103 reduces.
In addition, because side direction is advanced suppressed until when hook is in the top of altitude datum H1, mould 103 is therefore also reduced in the possibility of period with static object collision of advancing.Because altitude datum H1 comprises the additional void of the elevation-over 1m being in two stacking moulds 103, therefore, by the top of other moulds 103 that the mould 103 that supports will be in mould field.
Load transducer
Load transducer (not shown) is arranged for measurement and puts on the load at jack up unit 113 place and export payload data signal to Central Processing Unit (CPU) 125.The increase of the load detected at jack up unit 113 place applies corresponding to initial load when being promoted at first when load and dangle from hoisting crane 101 usually.During initial load applies, load transducer can detect the load of the increase comprising initial overload, and the load of this increase becomes stabilized conditions subsequently.Central Processing Unit (CPU) 125 is configured to ignore any overload measurement value and depends on and samples load cell signal at steady state.If detected load increases relative to the situation of roughly stabilized conditions after initial load applies, Central Processing Unit (CPU) 125 judges to hang the event of stumbling and the operation suppressing hoisting crane 101.
Central Processing Unit (CPU) 125 is configured to check that whether the mode of operation of hoisting crane 101 is suitable to judge the load detected.Central Processing Unit (CPU) 125 can filter application or perform with stored threshold value compare reduce the wrong possibility judging to have applied new load.In the present embodiment, the threshold value of 500Kg is used to determine whether to be applied with new load.When Central Processing Unit (CPU) 125 judges to be applied with unsuitable load, enable security protocol.The situation typical of application safety agreement is needed hereafter to illustrate by way of example.
When lifting frame 115 when not having corresponding lifting operation, laterally advance by direction, the increase of the load applied may be the instruction that hook has tangled static mould 3.Because applied force may make mould 3 be shifted, thus this is dangerous.Therefore, if lifting frame 115 carries out sideway movement when the increase of the load putting on jack up unit 113 being detected, then Central Processing Unit (CPU) 125 stops making the motion of hoisting crane 101.This advances at jack up unit, particularly important when such as advancing above altitude datum H1.Central Processing Unit (CPU) 125 can be configured to only make when hook is in above altitude datum H1 when the load of increase being detected the motion of hoisting crane 101 to stop.
When mould 103 is at first by lifting, there is the danger that load is waved due to lifting frame 115 and the misalignment of mould 103.As preventive, hoist cable operator should leave mould 103 when there is this initial lifting.This is initially promoted situation and is categorized as dangerous loading (LOUS) by Central Processing Unit (CPU) 125, and performs inspection to judge whether there is any hoist cable operator in internal security region 145 by thermal imaging camera 127.If load transducer detect the increment of applied load be greater than limit threshold value time hoist cable operator be in internal security region 145, then Central Processing Unit (CPU) 125 suppresses the lifting operation of jack up unit 113.The initial lifting of mould 103 can not be performed when detecting that hoist cable operator is in internal security region 145 by thermal imaging camera 127.Only as internal security region 145 nobody, jack up unit 113 can perform initial lifting operation.
Load is waved and is stopped when the center of gravity of mould 103 is positioned at immediately below lifting frame 115, and at this some place, mould 103 can be promoted safely.Five (5) seconds after there is initial lifting, load is waved and is considered to stop.Vibration duration depends on the distance between the center of gravity of load and winch 113.Therefore, will be appreciated that, the time may change according to the height of crane span structure 109 above mould 103.Therefore, after the scheduled duration that Central Processing Unit (CPU) 125 have passed through for five (5) seconds after the increase applied load being detected continue load transducer, mould 103 is categorized as safe loading (LOS).After initial lifting, when thermal imaging camera 127 judges that hoist cable operator has entered internal security region 145, after passing through this duration, allow the operation of jack up unit 113.
Load be divided into the classification of LOUS or LOS to be with reference to shown in the chart B in Fig. 6 with reference to the load applied that detected by load transducer.Chart B is in below altitude datum H1 based on the hook being connected to hoist cable 17a to 17d to prepare.
Load transducer can also be used for limiting the maximum load putting on hoisting crane 101.When load transducer detects the load being greater than and limiting threshold value such as 40 tonnes, Central Processing Unit (CPU) 125 can suppress the operation of jack up unit 113 and optionally remove some load in load.When hoisting crane 101 is operated in order to promote through being bolted to mould 103 of machine strut member, Central Processing Unit (CPU) 125 can make jack up unit 113 stop preventing from causing damage to mould 103 or hoisting crane 101.

As illustrated in figure 9 a, first hoisting crane 101 is shifted and leaves mould 103.Jack up unit 113 operates in order to lifting frame 115 to be risen prevent hoist cable 17a to 17d snarl away from any obstacle.Preferably, lifting frame 115 is fully risen, make the hook be arranged on hoist cable 117a to 117d be in the top of altitude datum H1 to guarantee that these hooks can not tangle any mould in mould field when lifting frame 115 marches to the mould 103 that will be transported.Crane operator 105 can by checking when the whether light judgement hook of the second lamp 155 on crane span structure 109 is in above altitude datum H1.When above hook is in altitude datum H1, Central Processing Unit (CPU) 125 allows hoisting crane 101 laterally to advance in direction with the work speed of routine.
Hoisting crane 101 is positioned at the top of mould 103 by crane operator 105, makes the center of gravity of the line of centers of fixed frame 115 and mould 103 roughly in a straight line.Crane operator 105 is responsible for positioning crane 101, and hoist cable operator 107 observes the motion of hoisting crane and assists crane operator 105 simultaneously.
As shown in fig. 9b, operate jack up unit 113 subsequently and fall to make lifting frame 115, thus make hook can be attached to attachment point 119a to 119d on mould 103.Lifting frame 115 carries out sideway movement until when hook is in below altitude datum H1 with the work speed of routine.When coder judge hook fallen into be in below altitude datum H1 time, Central Processing Unit (CPU) 125 start through suppress traveling mode to suppress the sideway movement of crane carriage unit 111; The work speed of jack up unit 113 is constant when lifting frame 115 is lowered.Hoist cable operator 107 guides hoist cable in place and when crane operator 105 sends signal by wherein two hoist cables 117b, 117d are attached to some 119b, the 119d of being relatively fixed on mould 103.When hoist cable 117a to 117d does not arrive corresponding attachment point 119b, 119d, crane operator 105 may need to reorientate lifting frame 115.Lifting frame 115 reorientate due to through suppress traveling mode startup and only can perform in progressive step.Due to mould 103 be not attached to lifting frame 115 and hoisting crane 101 not at the initial lifting operation of execution, thus while reorientating lifting frame 115, hoist cable operator 107 need not retreat to perch.Owing to there is no load applying in jack up unit 113 (as detected by load transducer), even if thus when thermal imaging camera 127 judges that hoist cable operator 107 is in internal security region 145, Central Processing Unit (CPU) 125 also can not be stopped using jack up unit 113.
Hoist cable operator 107 is by being attached to remaining two hoist cables 117a, 117c the process that be relatively fixed accordingly some 119a, 119c complete connecting mold 103 subsequently, as shown in Figure 9 C.
As shown in figure 9d, thus mould 103 is connected to jack up unit 113.But before starting to promote mould 103, crane operator 105 must check that whether jack up unit 113 is eccentric relative to mould 103.When jack up unit 113 is not placed in the middle, waving of load will be there is when mould 103 is promoted to leave bearing support.When crane operator is in outside safety distance relative to extraction clamping weight, hoist cable operator 107 moves to the perch outside internal security region 145 and sends signal.Load transducer detects load and when is applied in jack up unit 113, and when thermal imaging camera 127 detects hoist cable operator 107 (or other people) in internal security region 145, the operation of crane span structure 109, the operation of crane carriage unit 111 and the operation of jack up unit 113 are stopped.Only as the complete nobody in internal security region 145, hoisting crane 101 can be operated to perform the initial lifting of mould 103 (as determined by load transducer).Mould 103 is promoted to leave bearing support and is maintained in station until waving of any load weakens.As preventive, Central Processing Unit (CPU) 125 makes crane carriage unit 111 keep static a period of time after initial lifting, such as, keep static five (5) seconds.During this time out, waving of load can be weakened, and when load is considered to safe, hoist cable operator 107 can enter internal security region 145.At this moment after length, even if thermal imaging camera 127 judges that hoist cable operator 107 is in internal security region 145, Central Processing Unit (CPU) 125 is inactive jack up unit 113 also.Thus hoist cable operator 107 can send to crane operator 105 signal that lifting operation can proceed.Crane operator 105 activates jack up unit 113 with the top making mould 103 rise to altitude datum H1.
When mould 103 is in below altitude datum H1, starts the traveling mode through suppressing and suppress side direction to be advanced.Once mould 103 is in the top of altitude datum H1, then the traveling mode through suppressing just removed by Central Processing Unit (CPU) 125, and crane carriage unit 111 can be advanced with the work speed of routine.Crane operator 105 controls crane span structure 109 and crane carriage unit 111 subsequently to transport mould 103.
If mould 103 laterally direction advance while load transducer the increase of load applied at jack up unit 113 place detected, this may indicate and there occurs collision.Therefore, advance period in side direction, if load transducer detects the increase of applied load, then make crane span structure 109 and crane carriage unit 111 stop.
Process for being dismantled from hoisting crane 101 by mould 103 is contrary in order to the step being attached mould 103 with execution.But, when mould 103 is lowered, one or more hoist cable operator 107 may be needed to guide in place by mould 103, such as, mould 103 is positioned on strut member.Therefore, during falling operation, even if thermal imaging camera 127 detects there is people in internal security region 145, also still can operate jack up unit 113 and allow progressive side direction to advance.Central Processing Unit (CPU) 125 can fall operation with reference to judging when to perform with the one or more parts in lower component: load transducer, rotary encoder and control suspension apparatus.
Central Processing Unit (CPU) 125 is provided with override switch to cancel the restriction putting on hoisting crane 101.This override switch can such as hoisting crane at altitude datum H1 lower work time cancel through suppress traveling mode.Override switch can comprise mechanical lock or electronic lock.Override switch can work when unit failure or can work with the maintenance of convenient specific hoisting crane or calibration operation.It is contemplated that the lamp 153,155,157,159,161,163,165,167,169,191 in light display unit will glimmer to notify crane operator 105 and hoist cable operator 107 when surmounting control and working.
